OK, your real name is McGyver and you built it all with a Swiss Army knife, right?
This trailer is outstanding, has to one one of the top 5 builds on this portal.
We must think a lot alike! I used a strip of "rubberized" cloth material that I got from McMaster Carr industrial supply. This was glued with an adhesive made for motorhome applications. It appears to be a decent seal...but time will tell.I have a question. granted you live in an area that sees little rain but with the split upper bed having hinges how did you make it water tight? My only thought is maybe a piece of bike tire cut and glued in between. would love to hear your cure though.
Very cool build!!!
